Area of Science:

  • Neurosurgery
  • Surgical Simulation
  • Medical Education

Background:

  • Proficient open surgical treatment of cerebral aneurysms demands extensive training.
  • Developing effective simulation models is crucial for surgical skill acquisition.

Purpose of the Study:

  • To evaluate the validity of a human placenta aneurysm model for surgical simulation training in aneurysm clipping.
  • To assess the model's utility in teaching neurosurgical residents.

Main Methods:

  • 30 participants were divided into low, intermediate, and attending neurosurgical experience groups.
  • Subjective data collected via Aneurysm Clipping Participant Survey.
  • Objective data gathered using the Objective Structured Assessment of Aneurysm Clipping Skills (OSAA CS) tool.

Main Results:

  • The placenta model demonstrated high face validity, with 70% of attending surgeons rating it as realistic.
  • Content validity confirmed improvement in microdissection, clip application, and surgical techniques.
  • OSAA CS scores significantly differed across experience groups (P < 0.001), indicating construct validity.

Conclusions:

  • The human placenta aneurysm model is a valid and useful training tool for aneurysm clipping simulation.
  • The OSAA CS is a feasible instrument for quantitative assessment of aneurysm clipping skills.
